Method AbsoluteOffset¶
AbsoluteOffset method allows users to define home offset based on a user-defined absolute position offset. This method may be used when the distance between the encoder-zero and machine zero is known, for example when using an absolute encoder. The axis does not move. Homing switches, direction, velocities or inputs do not have to be configured.
Note
The state of the axis does not have to be Operation Enabled to execute this method.
In AbsoluteOffset method, home offset is calculated as:
HomeOffset = - AbsoluteOffset
The minus sign before AbsoluteOffset is necessary to achieve compensation.
